KINETICS OF COMBUSTION IN THE LAYERED Ni-Al SYSTEM

Combustion Science and Technology, 2001
Theoretical analysis and experimental results on the combustion in the Ni-Al layered system are presented. Combustion wave temperature and velocity were measured and microstructural and compositional determinations were made. The latter were made on products of complete combustion and on quenched samples using metallographic and electron microprobe ...

Optimizing Na and Rb Incorporation Along With Bandgap Grading for High Efficiency Ultra‐Thin CIGSe Solar Cells

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 10, Page 1238-1255, October 2026.
In this work, Na and Rb are incorporated into ultra‐thin Cu(In,Ga)Se2 (< 500 nm). By systematically varying the Rb content and combining predeposited Na with postdeposited Rb, we identify the optimal configuration, achieving solar cell efficiencies of 11.72% on Mo and 10.48% on ITO. Through electrical and compositional measurements, a mechanistic model

Effect of Nickel Addition on Corrosion Behavior of Laser–Arc Hybrid Welded Al-Mg-Si-Cu Alloy Joints

Metals
The corrosion performance of Al-Mg-Si-Cu laser–arc hybrid welded joints modified by 1.8 wt.% Ni remains poorly clarified. In this study, the corrosion behavior was examined via electrochemical measurements combined with SEM, EDS, and SKPFM.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐

Modeling Dislocation Cutting of γ′ Precipitates in Ni‐Base Superalloys: Linking Atomistic and Dislocation Dynamics Simulations

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
Dislocation cutting of γ′ precipitates in Ni‐based superalloys is investigated by linking atomistic simulations with discrete dislocation dynamics. The critical cutting stress is shown to be governed by the antiphase boundary energy, while line tension effects promote edge‐preferred cutting.
